A hydrogen-powered fuel charger is now available
You do not need to immediately imagine something like a system of something like a diesel generator and a set of gas cylinders that
The gadget consists of three parts, each of which is interesting in its own right, and together these elements make up a system that works according to the following algorithm: hydrogen production - filling fuel cells with hydrogen - transforming hydrogen into electrical energy. Where to get hydrogen? Where it is most accessible to us - in the water. The first part of the system, HydroFILL, extracts hydrogen from water by electrolysis, which we know from the school bench - 2H20 -> 2H2 + O2
It would seem stupid - energy is needed for hydrolysis, where can I get it? The developers also thought about this, providing HydroFILL with a solar panel. If there is an electric network near you, then you can use the usual AC adapter, the developers have provided for this too - but still it’s not so interesting, agree.
Further, hydrogen accumulates in Hydrostiks fuel cells, which are most reminiscent of finger batteries, both in appearance and size. The fuel cell fills for about an hour. In turn, Hydrostiks fuel cells are inserted into the MiniPAK charger (and, probably, into compatible gadgets that will appear in the near future - let's hope so). That's basically it. Difficult, but interesting.
True, expensive is a pleasure, I tell you. A HydroFILL hydrogen generator costs $ 500, a MiniPAK charger costs $ 100, and each Hydrostik costs another $ 10. Although it does not bother to stock up, who knows when the energy crisis will manifest itself. All in all, if you have an extra $ 650,
For comparison, a standard battery is six times inferior to a hydrogen battery in energy consumption. Hydrostik is capable of storing 12 watt-hours of energy, but a regular AA-sized battery is only 2 watt-hours (at best).
In general, despite the relatively high price, the device deserves our attention and most likely will occupy its niche.

UPD. It turns out that the solar battery is not supplied for free, but for some 650 US dollars. So add this to the total cost of the device.
